I started to remake another version of my old fire trucks design this time its a Fire Command Vehicle. Background for this is that it goes together with the previous fire truck which provides information of the surrounding area to the other dispatch trucks. I wanted something big to show the Heavy Industrial presence after seeing many CAT Heavy tractors and Machine vehicles along the way to work.
Here is the process I took using sketchup as a base model.
Quick sketches of the VW Van and Trucks. Plus other practice observations. All these were done in Pilot Hi-Tec C4 Pens
Doing a wheels study from various vehicles in freehand.
A house by the sea sketch and the bubble tower study.
